' Specilication forming part of Letters Patent No.- 48,468, dittcdllunc 27, 1865.

` To all whom it may concern:

'Be it known that I, P. WER .,M, of VBerlin, in

`the county of Holmes and Sta e of Ohio, have i invented certain new and'uset'nl Improvements `in a StaveJointer; and I do hereby declare that the following is a full and complete de' scription of the construction and operation of )the same, reference being had to the accompacation, in whichnying'drawings, making a part'of this specifi,-

Figure 1 is a plan view.

Fig. 3 is an end elevation.

j Like letters of reference denote like parts in lthe several views.

. My improvement relates to a'stave-'machine y so constructed thatstaves of any size' for kegs yor barrels canl be made tapering at ends and @cut the desired bevel on the sides b y Vone con- "tinuous operation.V

In the several gure's A represents the stat tiona'ry supporting-frame, suitably constructed to be adapted tothe various operating parts. B is a moving or slidingframe, the side pieces "of whichare cut `or grooved out, so 4as to fitv jo'nto pieces a of the stationary frame, on which fit slides. v

C C are adjustable frames,` arranged on the of the saws'` i j r The upper part ot' the frames are formed into a box or bed, into which a rectangular frame, E, tits, the ends of the frames C being under- .i neath and extending uponthe sides of thel frames E. Theframes E caribe adjusted ver-- tically in the boxes by means of ascre-w, c, u udeineath, (seen in Fig. 3,)-whi'ch, by screwing Y or unscrewing the inner end of the frames, can

be moved up or down, increasing or decreasing .the inclination of the saws. i The shafts Clv of the saws are supported and turn inthe trames E, there being caps screwed down on the top bythumb-screws b, the holes in the caps and journals being so arranged as to be adapted to anyinclination into which the shafts may be' adjusted.

. There are pulleyse on the shafts U', to which, the power is connected that operates the saws.

Fig. 2 is a side elelhe frames C can be moved-'laterally on the stationary frame, increasing or decreasing the distance between the saws .by means of slots. (shown in Fig. 1,) andV screw-bolts k, by which 'the frame can be .loosened and nl oved either way to or from each other and then firmly secured in the desined position. These adjustab'le frames move in -a direction at right angles to the sliding frame or carriage B. j

-On the slidingfram'e Bis arranged the staveholder, that consists of a rest, G, supported in socket-standards H, secured to theframe. The rest is connected to the standards H by means i of standards extending down from the rest into the sockets, and are held in place by set-screws h, by which the rest can; be adjusted up lor down and held in any desired position. -By

means of this adjustment various widths ot' staves can be sawed upon the sanieradins with out changing the position of the saws, fortbe changing of these to suitlvarious widths ot' staves involves the 'necessity for a double adjustment, one for the width and one for the radial line for each saw, making four adjustments. A 1

At one end ot', t-herest G rises a standard, I, upon which is a cross-bar, l. 'llo each end of lthiscrossbar 1 is secured by bolts the iingers g g, the lower ends of which. agree in posi tion with the catch J. Thengersare adj usta ble, and their properposition-is on aline just outside of the line of the saws, and their incliv'nationis the s'ameasshownin Figg. '.Eiiecatch Y J is attached tothe rest Gin the' positionshowd in Fig. 1, and its front or catchiend isn'early i y on a linewith the lower 'end-ofthe fingers g g. The catch J' is narrower thanthe'. staves to be sawed, and when "theendofthe staveV isginserted` beneath Y, the Vcatch J the 'outer edges l pass underth-e'ends offtbeiingers g g, for the purpose hereinafter described. 1 y

L represents an arch or support placed upon the middle of theffrest G, fdrisnpporting the middle of the stave'when it'. is bent into the proper curve for sawing; At the other end ot' the rest'there i's a curved "standard, m, to which 'f is connected acurved lever, n, that is turned on `onoi' theend of the stave. q

Thefmann'er,ooperating this machine is as follows The-"timber off'r whichthe stave isto the madeisplacedin the holder. ,V One endlis put stave.

2 'estese under the catch J and the other end is bent down over the arch L, when-the lever a is turned down on it, holding it securely.A Thus the timber is bent in the desired forni for the The frame B is then moved along, as before stated, bringing the timber between the saws from end to end, which saws it thc, desiredbevel on both sides the whole length and tapering toward the ends.

It will be observed that the higher the timber is carried between the saws the wider will be thestave; and for the same reason the middle of the timber that is to form the bulge of the barrel being curved upward from the ends will be sawed gradually wider or tapering toward the endsin the desired mannero The bevel on the edges ofthe stave is sawed at the same relative angle at the middle as at the ends, varying according to the increased diameter from the ends to the middle of the barrel.' In this way the stave is cut ont and shaped from end to end and on the edges in the mostperfect mannergby one continuous operation.

The saws can be inclined more or less by means of the adjustable frames E and screwbolts c, as before described, and the saws can be adiueted laterally to suitthe width of the staves to be cut.` TheirestG, on which the staffe is held, can also be raised or lowered. Thus the machine can readily be adjusted in 'various ways to saw any sized or shaped staves of any length that may be required for kegs, casks, or barrels.

The ngers g. come down on the timber of which the stave is to be cut each side of the catch J, so as to ,prevent the pieces that are sawed oft' from catching on the saw and being carried round, as it was found 'they were liable to do, 'and strike the person operating the ina' chine. What I claim as my improvement, and de- .sire to secure by Letters Patent, is-

'lhe sliding frame B, the adjustable sawframes C C E E, the adjustable'rest G, and arch' L, the catch J, fingers gag, and curved lever u, when these several part'sare arranged so as to operate'a's and for thepurpose setforth'.
